add to favorites Grinding wheel particle size selection Pc  

The particle size of the grinding wheel is to crush, roll and process the smelted crystal block, and then screen the fine powder of different sizes of particles, wherein the particle size is represented by a number, which is called particle size. The particle size is generally expressed by the number of the sieve, that is, the sieve hole per inch length, and the larger the number, the smaller the abrasive grain.

thin flat cutting discGranular choice

The wheel size is a measure of the size of the abrasive particles. The choice of grinding wheel size directly affects the surface roughness and grinding efficiency of the workpiece. In general, the grinding efficiency is high when grinding with a coarse-grained grinding wheel, but the surface roughness of the workpiece is poor. When grinding with a fine-grained grinding wheel, the surface roughness of the workpiece is good, but the grinding efficiency is low. In short, under the premise of meeting the surface roughness requirements of the workpiece, the abrasive tools with coarser grain size should be selected as much as possible to ensure high grinding efficiency.

Usually the choice of grinding wheel size is determined according to the grinding needs. usually:

Rough grinding: steel ingots, forged castings, leather wood, cut steel billets, etc., for 12#. 30#

Semi-finishing: used for rough grinding of plane, outer circle, inner circle, centerless grinding, etc., applicable to 36#

General fine grinding: used for outer circle, inner circle, plane, centerless, tool grinding machine and various special grinding machines, etc., applicable to 60#

For fine grinding, honing, threading, etc., for 120# one W20

Super fine grinding: fine grinding, super fine grinding, mirror grinding, etc., for W20

add to favorites Vibratory mill is a special grinding mill Pc  
No Picture

A vibratory mill having a long, thin milling chamber which spirals upward in a conical arrangement from a center location within a housing to a point at the periphery of the housing. The configuration of the chamber improves the efficiency of the mill and promotes the use of a continuous operation rather than a batch process. Eccentrically mounted rotating weights cause the media and parts to migrate upward from a central receiving position to the periphery of the housing.

This is the first mill we will consider which does not rely on rotation for the main grinding action. The vibrating mill is a grinding mill which is filled to about 65 80% of its capacity with grinding media such as balls or rods. The chamber is vibrated at a frequency of between 1000 and 1500 times per minute (can be variable speed) by cams or imbalanced weights.The grinding action is efficient and thorough. Grinding media material and chamber lining can vary depending on application.

Vibrating mill can grind hard or soft materials. Maximum throughput is in the order of 20 t.p.h. but feed size should be kept fairly small. Although final product size can be as low as 0.005mm this type of mill is often used for less fine applications. Product size and shape is a function of the time spent in the mill, media type and size, and frequency of vibration. Commonly functions as a batch mill.Material suitability for vibratory mill: Lime, Calcium carbide, Alumina, Gypsum, Bauxite, Chromitem, Limestone, Sillimanite, Fluorite, Pigments, Dolomite, Magnesite.

Vibratory mills are the most versatile line of mills available today for fast, low-cost particle size reduction to sub-micron range. The raymond mill action achieves higher output per input horsepower; precise control of size and distribution. Product contamination from media and lining wear is virtually eliminated. Maintenance costs are low because of few moving parts and replaceable linings made of abrasion-resistant metal, ceramic or elastomers.

The Vibratory Mill's unique vibratory motion, coupled with the use of cylindrical media, allows a dense packing of the media bed assuring maximum media surface contact and minimum void area when operated under a low energy condition. Feed materials as large as 300 microns can be reduced to sub-micron sizes.In the high energy configuration, feed materials as large as twelve inch agglomerates have been successfully milled and solid particles of a half inch are being reduced to a d50 of less than 5 microns low energy condition is reserved for wet milling whereas the higher energy mode can be used either wet or dry.

Stainless steel is a type of metal that has a degree of corrosion resistance in the atmosphere or in certain corrosive media. Because of these advantages, it is widely used in different industries of the current society. Stainless steel grinding burns have been plagued by grinding. Briefly introduced the classification of stainless steel and the characteristics of stainless steel grinding, stainless steel grinding burns and solutions.

One: 7" cut off disc for stainless steel classification:

Martensitic stainless steel (common grades are 1Cr13, 2Cr13, 8Cr13, 1Cr17Ni2, etc.)

Ferritic stainless steel (common grades are 0Cr13, 1Cr14S, 1Cr17, 1Cr17Ti, etc.)

Austenitic stainless steel (common grades are 1Cr18Ni9Ti, 0Cr18Ni9, 1Cr18Ni9, etc.)

Precipitation hardening type stainless steel (common grades are 0Cr17NiCu4Nb, 0Cu17Ni7Al, 0Cr15Ni7Mo2Al, etc.)

It can be classified into a Cr system (SUS400), a Cr-Ni system (SUS300), a Cr-Mn-Ni (SUS200), and a curing system (SUS600).

Two. Features of grinding stainless steel:

1. Stainless steel has high toughness and high heat strength, while the cutting edge of the grinding wheel has a large negative rake angle. During the grinding process, the grinding debris is not easily cut, the cutting resistance is large, and the extrusion and friction are severe. The grinding force per unit area is very large, and the grinding temperature can reach 1000 ° C ~ 1500 ° C. At the same time, under the action of high temperature and high pressure, the grinding debris is easy to adhere to the grinding wheel, filling the gap of the abrasive particles, so that the abrasive particles lose the cutting effect. The type of stainless steel is different, and the condition of the grinding wheel is different.

2. The thermal conductivity of stainless steel is small, the high temperature during grinding is difficult to output, and the surface of the workpiece is easily burned and annealed. The depth of the annealed layer can sometimes reach 0.01 to 0.02 mm. Severe fracture deformation during the grinding process results in work hardening on the abrasive surface. In particular, when austenitic stainless steel is ground, the austenite structure is not stable enough, and martensite structure is likely to occur after grinding, and the surface hardening is severe.

3, stainless steel has a large coefficient of linear expansion, which is easily deformed under the action of grinding heat, and the size is difficult to control. This is especially true for thin walls and elongated components. Most types of stainless steel cannot be magnetized. In the case of surface grinding, the workpiece can only be clamped by mechanical clamping or special clamps. The workpiece is clamped to the side of the workpiece, causing deformation and shape or dimensional errors. protruding. At the same time, it also produces jitter and scale-like ripples during the grinding process.

add to favorites Evaluate the shape of the grinding wheel Pc  

Because the surface of the grinding wheel directly affects the quality of the grinding surface, it determines the grinding performance and service life of the grinding wheel. Therefore, it is of great significance to evaluate the grounding of the wheel after trimming, and it can be used to guide the design of the wheel dresser and the dressing of the grinding wheel.

1. Ideal grinding wheel shape and its evaluation

The state of the thin abrasive cutting disc for metal can be used to predict the amount of grinding surface. In order to make the distribution of the cutting marks on the surface of the workpiece to be more uniform and reduce the roughness of the grinding surface, the grain spacing of the surface of the grinding wheel should be uniform; at the same time, in order to make the grinding particles in the grinding

The depth of the cutting marks on the surface of the workpiece is uniform, and the surface roughness of the surface is small. Therefore, the height distribution of the surface of the grinding wheel is uniform, that is, the contour is good; and in order to use the micro-knife in a semi-blunt state under appropriate grinding pressure The friction generated between the surfaces of the workpiece acts as a polishing device to obtain a grinding surface with high precision and small roughness, achieving high precision, small roughness, and grinding. Therefore, the particles on the surface of the grinding wheel should have the micro-knives described above. The ideal wheel has the three characteristics of uniformity, uniformity and micro-blade.

The ideal evaluation of the quality of the grinding wheel is as follows. The ideal wheel topography should have three characteristics. In order to make the abrasive grain distribution on the surface of the grinding wheel uniform, the surface of the thin flat cutting disc should obey the following two directions.

Uniform distribution on the uniform distribution of abrasive grains in the width direction of the grinding wheel and uniform distribution of abrasive grains in the circumferential direction of the grinding wheel

The intrinsic quality of diamond grinding wheel is mainly affected by abrasive, particle size, concentration, binder, filler and hardness and strength. Electroplating Ni-based bonding agent, high strength, large abrasive holding power, good shape retention of thestandard cut off wheel for metaland long service life, but its self-sharpness is poor and the adaptability is poor. Resin bonding agent: low strength, small abrasive holding force, abrasive grain Good properties, sharp surface of grinding wheel, high grinding efficiency: but not wear-resistant, low life; metal bond, grinding performance between electroplating and resin bonding agent, good overall performance.

The coarse grain size of the diamond will reduce the cutting wheel load, improve the cutting efficiency, and extend the life of the grinding wheel, but the collapse is large; the fine particle size will reduce the cutting and fracture, and reduce the surface roughness: but the life is short. The grinding wheel has a high concentration: the grinding wheel has a large number of abrasive grains, a single abrasive grain has a small grinding force, wear resistance, and the grinding wheel has a long service life: but it should not be too high. Filler is also the main method to improve the performance of the 7" cut off disc for stainless steel Adding alloy powder can improve the rigidity and wear resistance of the grinding wheel, and adding ordinary abrasive grains can improve the sharpness of the grinding wheel. The hardness and strength of the grinding wheel are high: the abrasive grain is not easy to fall off, and the wear life is high: but the sharpness of the grinding wheel is poor: it is easy to affect the quality of the grinding workpiece. For specific use, adjust according to different grinding conditions: to adapt to its comprehensive grinding performance.

The geometric accuracy of the grinding wheel has little effect on ordinary grinding, because the working face of the grinding wheel often has to be repaired on the machine. When the electronic components are precision cut and ground, the thickness of the ultra-thin grinding wheel is no longer trimmed, so the geometric accuracy of the cutting and the accuracy of the shape and position must also be taken seriously. The difference between the thickness of the grinding wheel and the large impact of the end face affects the cutting precision: there is competition; the inner hole of the grinding wheel is too large, the inner and outer circle concentricity is not good, and the grinding vibration is easy to occur: the workpiece is collapsed; the flatness of the grinding wheel is poor, the symmetry is poor, The difference in the perpendicularity between the outer circle and the end surface is likely to cause the cutting and eccentricity of the cutting: a beveling phenomenon occurs. In order to further improve the grinding and cutting effect of the grinding wheel, the optimization of the grinding wheel structure can also have a certain effect. For example, if the side back angle is set on both sides of the grinding wheel: it is beneficial to improve the cutting precision; the outer circle of the grinding wheel is provided with an arc: it can improve the cutting and collapse; the water tank is set in the outer circle of the grinding wheel to improve the chip removal ability: reduce the grinding temperature: However, the impact of the wheel with the sink and the workpiece can not be underestimated.

add to favorites Summary of three ways of efficient grinding Pc  

High speed grinding

High-speed grinding is a process that increases the removal rate of grinding and the quality of grinding by increasing the linear speed of the diamond wheel. Relative to the 7'' cut off disc for metalproduct application,High speed grinding has the following advantages:

(1) Under a certain unit time grinding amount, when the linear speed of the grinding wheel is increased, the cutting thickness of the abrasive grains is thinned, so that the load of the single abrasive grain is reduced, and the durability of the diamond grinding wheel is improved;

(2) Reduction of surface roughness of grinding: After increasing the linear speed of the diamond grinding wheel, the cutting thickness of the abrasive grains becomes thinner, so that the relative feed amount of the grinding wheel becomes smaller and the roughness is also reduced.

(3) The reverse grinding force is reduced and the accuracy of the workpiece is improved.

2. Slow-feed to deep deep grinding

Slow-feeding Large-depth deep grinding is also called deep groove grinding or peristaltic grinding. It is ground with a large grinding depth (up to 30mm) and a very low table feed (3-300mm/min). The required dimensional accuracy can be ground by one or several passes. The advantages of slow-feeding and deep-depth grinding are:

(1) When the retarding is applied to grinding. The grinding wheel and the outer edge of the workpiece are only contacted once or several times, and the chance of impact is less than that of the general reciprocating grinding, which can extend the durability of the grinding wheel and maintain its forming precision.

(2) The workpiece feed speed is very low during deep grinding, which makes the radial feed rate of the grinding wheel lower and the radial wear is relatively small. Conducive to rough, fine grinding of complex shaped workpieces.

(3) The grinding depth of the grinding wheel for slow-feed grinding is about 1000 times larger than that of ordinary grinding, and the grinding force is increased by 2-4 times (under the same metal removal rate) than that of ordinary grinding.

3. Abrasive belt grinding

Abrasive belt grinding uses high-speed moving abrasive belts as grinding tools. The method of grinding various surfaces is called belt grinding. The advantages of abrasive belt grinding are:

(1) High production efficiency, sharp abrasive grains on the abrasive belt, large cutting amount; sand bandwidth, large grinding area, and productivity 5-20 times higher than grinding with grinding wheel;

(2) The grinding energy consumption is low, because the belt is light in weight, the contact wheel and the tensioning wheel are small in size, and the high-speed moment of inertia is small, so the power loss is small;

(3) Good processing quality, can guarantee constant speed work, less heat, no need to trim, sharp abrasive grain, good heat dissipation condition of sand belt, high precision and small surface roughness value

(4) The belt is soft and can be applied to the forming surface for grinding, which is suitable for grinding various complicated shapes.In fact, thin flat ,thin flat cutting disc are matched with these advantages.

The disadvantage of abrasive belt grinding is that the belt is consumed quickly, the belt grinding cannot process small diameter holes, blind holes, and the step outer circle and gear can not be processed. Of course, when using high-speed grinding, it is necessary to confirm that the working speed of the machine tool must be lower than the safe use line speed of the grinding wheel, and the use of slow-feeding to deep-depth grinding also ensures the safety during grinding.

In recent years, China also begins to pay attention to the reasonable use of materials resources, put forward many policies such as consumption conservation and emission reduction, and conducts a lot of practical research, such as traditional collection and recycling and application of waste brick and stone materials in gardens and avenues. The recycled building materials are lower in prices compared with common building materials, so that they are well received in the market. In order to effectively resolve the city building waste problem, the government department in many cities passed the decision of taking advantage of building waste disposal equipment to process the building waste, carried out the strategy of collecting and recycling the building waste and researched the application situation of the building waste disposal equipment in the market. The professional building waste disposal equipment produced by us, portable crusher plant is able to process about three thousand tons of building materials every day, part of the wastes are used as baking-free brick materials by the local brick manufacturing companies, and the rest of the concrete aggregates are used as water-stable layer materials in municipal administration avenues.

Because the building waste is stocked in a concentrated place, the storage place is limited and the transportation is not very convenient, at this time, the workers can make use of mobile building waste crusher in order to conduct multi-level crushing to large-sized materials. The equipment covers a small space so that it will save a lot of infrastructure construction and removal cost. In addition, this machine is able to crush the materials in the working site so that it will not need to transport the materials to other places to be crushed, so that the materials transportation cost will be greatly reduced. And what is more, the building waste crusher can also be redesigned and reshaped according to the actual spot so that it is the most ideal equipment for processing and handling the building waste. Other than the mobile crusher, other crushing and grinding machines such as ball mill researched and developed by us also enjoy great popularity.

High-speed grinding is the development trend of today'sChina cut off disc . More and more grinding machine design or grinding requirements are developing at high speed, and the advantages of high-speed grinding; 1. Increased production efficiency, high speed machining speed and low time consumption 2. The surface roughness is reduced, high-speed grinding can improve the grinding frequency, avoiding the insufficient grinding strength of slow grinding and the damage of multiple grinding. 3. The grinding temperature is low, the grinding time of high-speed grinding is short, and the grinding temperature is too late to rise. 3. Make full use of the high hardness and high wear resistance of superabrasives, and the performance is fully utilized. High-speed grinding is not as fast as possible. He has some bottlenecks that limit the speed of grinding. 1. Grinding wheel strength requirements, although the grinding wheel has the characteristics of high strength and high wear resistance, but also requires dynamic balance, otherwise it will cause problems such as cracking of the grinding wheel. 2. Resting technology of super hard grinding wheel. In order to reduce costs, wheel dressing is necessary, but the grinding wheel correction technology affects the speed of high speed grinding. 3. Coolant pressure and nozzle design, the coolant is to avoid workpiece burn caused by instantaneous high temperature. Therefore, a suitable coolant is required, otherwise the processing speed is reduced when the temperature is too high. 4. The rigidity of the main shaft must ensure the rotation accuracy, thermal stability and dynamic balance during high-speed machining.

For the ultra-thin grinding disc with high quality grinding disc factory price, I don't know how much you know. However, it can be confirmed that the grinding disc cutting piece is very helpful to the large machinery industry, such as the cutting of steel pipe. If there is no cutting piece, there is no way to cut it. Therefore, its application There are also many. Ultra-thin cutting blades are also called ultra-thin grinding discs for stainless steel tubes, capillary tubes, glass tubes, quartz tubes, automotive exhaust pipes, brake wires, tungsten wires, molybdenum wires, copper wires and other pipe and filaments. The cutting has a good effect on the cutting of special steel and the slotting of the workpiece. So, what is the processing technology of ultra-thin grinding disc? Below Henan abrasive grinding tools manufacturers come to talk to you. 1. Grinding disc with high quality grinding disc factory price cold pressing process: the bonding agent used is wetting agent and powdery resin. It is usually used as a wetting agent with liquid phenolic resin, furfural, decyl alcohol, cresol, etc. The most used is liquid phenolic resin. 2. The semi-hot pressing process of the grinding disc: the pressing temperature is generally 50-65°C, the viscosity of the liquid resin becomes smaller at this pressing temperature, and the powdery resin can be well integrated, so that the fluidity of the whole resin system is improved. It is easier to fully penetrate the various spaces. Even if the pressure of the press is not too high, it can be molded well, and the holding time does not need to be too long. It is especially suitable for the automatic pressing production line for continuous operation. 3. Grinding disc with high quality grinding disc factory price hot pressing process: mixing requirements are different from cold pressing process. Generally, dry mixing method is used, or 1% of furfural less than the weight of abrasive is used as wetting agent to wet the abrasive, and then mixed with powdered resin evenly. Although the ultra-thin grinding disc is easy to use, we must pay attention to the safe use during the use. For example, when using ultra-thin grinding disc with high quality grinding disc factory price, the operator should wear protective glasses, masks, earplugs, gloves, dustproof clothes. When working on ultra-thin cutting blades, stand on the side of it, and do not operate on the front side, so as to avoid the failure of the cutting disc of the grinding disc to fly out or break out and hurt people. After all, this is working under high-speed rotation.
add to favorites Grinding Wheel Grinding Problem Pc  

In the process of grinding the grinding wheel, the vibration is caused by external disturbance or the unreasonable way of construction feeding, which reduces the quality of the machined workpiece. The problem of grinding the vibration pattern is very common and has been widely criticized in the industry. An in-depth understanding of the causes of the occurrence of vibrating during the grinding process can help companies improve the production efficiency of cut off disc for stainless steel and reduce production costs.

1. Reasons for grinding vibration

When using grinding the cutting disc, according to the characteristics of the vibrating pattern of the observed workpiece, it is found that the fluttering vibration pattern of the grinding surface can be divided into three types: spiral curved shape, linear type and spotted type, wherein the spiral type vibration pattern is trimmed by the grinding wheel and the diamond. The vibration generated between the pens is caused by the poor rigidity of the grinding wheel spindle or by external disturbances: The linear vibration pattern is caused by the imbalance of the grinding wheel, especially in the inner circle grinding. When the grinding wheel is milled or the blockage is uneven and the regeneration effect is also easy to appear linear vibration on the surface. Finally, the spot type vibration pattern is caused by local vibration caused by uneven hardness on the circumferential surface of the grinding wheel.

 2. Impact on the workpiece:

Firstly, the generation of the grinding vibration has a great influence on the life of the workpiece, and the vibration is more likely to cause corrosion. If it is for the bearing, it will mainly affect the accuracy of the workpiece rotation during use. When the vibration is measured, the vibration value is not round enough, and in the case of severe vibration, the vibration of the grinding line is caused.

 3. Solution

When the grinding wheel is finished grinding, the grinding wheel characteristics are selected reasonably (such as uniform hardness, slightly coarser grain size, loose structure); timely replacement of the dressing device of the grinding wheel: often finely dressing the grinding wheel: Balance the grinding wheel to achieve accuracy: Ensure uniform feeding To improve the rigidity of the equipment, the grinding allowance of the blank should not be too large and so on. These precautions can be noticed at ordinary times, which can greatly reduce the occurrence of grinding and vibration problems. Thereby improving the efficiency of processing.
